I am working to make sure we don't only protect the environment, we also improve governance.

For me, one of the major reasons to move beyond just the planting of trees was that I have tendency to look at the causes of a problem. We often preoccupy ourselves with the symptoms, whereas if we went to the root cause of the problems, we would be able to overcome the problems once and for all.

We all share one planet and are one hummanity, there is no escaping this reality.

I think [GMO] is one area where the is a need for legal regulations to make sure that companies - because at the moment, companies are the ones that have this technology - will not use this technology in a way that could adversely affect the people.

In Kenya, one of our biggest exports is coffee. Where do you grow coffee? You grow coffee in the land. To be able to grow coffee you need rain, you need special kinds of soils that are found on hillsides, and that means you have to protect that land from soil erosion so you don't lose the soil. You also want to make sure that when the rains come you're going to be able to hold that water and have it go into the ground so that the streams and the rivers keep flowing and the ground is relatively humid for these plants.
